ADAPTATION OF CONIFERS 115 



Irish juniper, var. hibernica, is a compact, pyramidal or 

 columnar form. It does best in damp but perfectly drained soil 

 and is quite hardy in the Middle West. It requires copious and 

 frequent watering during the summer months. It is valuable 

 for formal planting in gardens and lawns. Propagation is by 

 cutting or grafting. Swedish juniper, var. suecica, is quite 

 similar to var. hibernica, but grows higher and is of a lighter 

 and more bluish color and the branches do not grow quite as 

 stiff and compactly. In general the form is pleasing and useful 

 where formal effects are desired. It is propagated from seeds, 

 cuttings, and grafting. 



Juniperus horizontalis is a trailing or creeping form em- 

 ployed for ground-cover and edging garden walks. It is propa- 

 gated from cuttings and layers. The Waukegan juniper, 

 var. Douglasii, is an interesting creeping form. It seems to 

 love the sand and gravelly soil, yet it will do equally well in 

 rich garden soil or on rocky slopes, banks, and terraces. The 

 color of the foliage is a soft blue in spring, changing to a rich 

 purple color in the fall. This form is very useful for wall- 

 covering, rock-gardens, and edging of walks. It is a rapid 

 grower and easily propagated from layers taken in early 

 October and planted in lath frames in a sharp sand. The 

 plant thrives on sunny slopes and does equally well in partially 

 shady situations. 



Jwiiperus scopulorum is a narrow, compact, symmetrical 

 form with one single stem. It grows well in the North and 

 South. It is valuable for landscape effect on account of its 

 close, compact and erect habit and beautiful silver foliage. 

 Propagation is by cutting or grafting on allied stock. 



Juniperus Sabina is very hardy, of erect habit, with numer- 

 ous spreading branches. It is useful for a foundation for other 

 trees. The plant does best in a dry, gravelly, sunny situation.
